Wide variety of combinations can cope with variousneeds.
External Vacuum Controller for Vacuum Pump Series is for
available
For the pipe lead-out direction of concentrated piping of
manifold-type, two types are available; front lead-out
typeand rear lead-out type.
It is designed to adjust the breaking flow and breaking pressure at the same time to prevent scattering or locking of work
piece which is difficult to control by only breaking flow adjustment.
By adding a relief function to the vacuum breaker circuit, the vacuum breakdown time has been shortened for the first
time in the industry.
The vacuum sensor is an LED-indicated digital sensor (V4).
The basic specification : 2 switch output and analog output
Standard nozzle bore: 05(ø0.5mm), 07(ø0.7mm), 10(ø10mm) and 12(ø1.2mm).

① Tube insertion
In the characteristics shown above, supply pressures refer to those when vacuum is generated.
In the characteristics shown above, an odd noise may be heard when supply pressures are immediately
before the peak of vacuum levels (H (High vacuum) type: 0.4~0.45MPa, and E (High-vacuum at low air
supply pressure type) type: 0.29~0.32MPa). The sounding of this odd noise means the characteristics
are unstable. If nothing is done, the sound may become even noisier. This situation can also adversely
affect the sensor, resulting in a malfunction or trouble. So reset the supply pressure.
(Ex. 1: When the vacuum generator H type is in operation with the original pressure of 0.5MPa, the
odd noise began to be heard due to a drop in supply pressure to 0.43MPa. Reset the supply pressure
for the vacuum generator in operation at 0.5MPa.)
Piping design and equipment selection should be made with an effective sectional area being 3 times as
large as the nozzle diameter as a standard. Satisfactory vacuum characteristics are not obtained unless
sufficient supply air flow is secured.(For example, the odd noise is heard even when pressure is at the set
value, suction flow is insufficient, the final vacuum does not satisfy the required level, etc.) (Example2.
There is the odd noise from the vacuum generator H type, though the supply pressure is 0.5MPa. →
Insufficient supplied air rate is the cause. The supplied air rate is reduced before the vacuum generator
by a pipe resistance, and a proper air rate is not obtained. Select tubes and pneumatic apparatuses with
the target effective cross-section areas obtaining the necessary air flow rate.) (Example3. When
ø1.0mm of nozzle bore is selected, the effective cross-section size should be more than
2.35mm2.(cross-section 0.52xπ=0.785mm2x3=2.35mm2). Select tubes and pneumatic apparatuses with
the effective cross-section area more than 2.3 mm2.)
Insert a tube into Push-In Fitting of the vacuum generator VK up to the
tube end. Lock-claws bite the tube to fix it and the elastic sleeve seals
around the tube. Refer to “2. Instructions for Tube Insertion” under
“Common Safety Instructions for Fittings”.
Characteristics
1. How to insert and disconnect
② Tube disconnection
The tube is disconnected by pushing release-ring to release Lock-claws.
Make sure to stop air supply before the tube disconnection.
In order to fix the vacuum generator VK, tighten M3
threads through the fixing holes on the resin body with
tightening torque 0.3 to 0.35Nm. Refer to the outer
dimensional drawings for the hole pitch.
For general type and check valve internal waste, the position
of the cabinet is different. Please refer to this information.
2. How to fix the product

Warning
caution
Detailed safety instrution
Please read it before use, Appendix-P.38 for 'Safety Precautions', Appendix P.40 for 'Common Precautions
for products', and Appendix P.44 for 'Common Precautions for Vacuum Equipment'.
Make sure that the leakage current is less than 1mA, when operating a valve unit. Leakage current larger
than that may cause malfunction.
Vacuum generator with vacuum retention function permits some vacuum leakage. Provide an appropriate
safety measure when vacuum retention for long period of time is required.
The coil in a pilot solenoid valve generates heat under the following ①-③ conditions.The heat may cause
dropping life cycle, malfunctions and burn or may affect negatively on peripheral machines. Contact us when
the power is applied to the vacuum generator under the following conditions:
①The power is continuously ON for over 2 hours.
②High-cycle operation.
③ Even when intermittent running of the generator is carried out, the total operation time per day is longer than
non-operation time.
Regarding double-solenoid types (VJ□□A…), the switchover valve (main valve) is placed in neutral after
the supply of pilot air has been suspended (the same is true when the valve is being operated for the first
time after shipment). When resuming the supply of pilot air, be sure to send a signal to the pilot valve, or
conduct switchover operations manually as required.
Do not give an excessive tensile strength and bending on a lead wire. Otherwise, breaking wire or damage
on connector may be caused.
When manifold type is selected, dropping the performance or having an effect to other vacuum ports can
be caused depending on number of stations or a combination of mounting units. Contact us for any unclear
points.
Compressed air contains many kinds of drains such as water, oxidized oil, tar and other foreign substances.
Dehumidify the compressed air by using an after-cooler or a dryer and improve the air quality, since those
drains seriously impair the performance of the vacuum generator.
Do not use lubricators.
Since pipe rust cause malfunctions, a filter finer than 5μm should be placed right before the air supply port.
Do not use the vacuum generator under the condition of corrosive and / or inflammable gas. Also do not
use these gasses as fluid medium.
Do not operate a blow-off valve during vacuum generating.
When replacing vacuum port cartridge, first remove any foreign substances clinging to them and the
surrounding areas, then firmly insert pins into cartridges.
When replacing a supply port block, make sure not to lose the seal rubber and remove the foreign substances
stuck around the block. Tighten the screw to fix the block with 0.27-0.3Nm of the tightening torque.
For check type, if the vacuum port is closed when the vacuum is blown-off, the residual pressure in the check
valve may be applied and vacuum switching may not be possible.
In above case, disassemblling vacuum filter module will release residual pressure and it will operated again.
